Big dangerous Russia, environmental thief or house warmer? The Nord Stream pipelines are a highly debated theme in Europe and the EU. A number of different countries will be subject to the pipelines direct or indirect. This paper aims to figure out what kind of threats and possibilities Denmark, Finland, Sweden and Germany consider to be the consequences with the pipelines.The study takes as a standpoint the area of security studies and the widened of the same. The three standpoints within the security study that will be used are military security, environmental security and energy security.

Abandoned and unused railway structures often possess great potential if they are reclaimed and reused for new purposes. The thesis focuses on the global trend of restoring and revitalizing these areas, converting them into park areas, rail trails and green corridors in the city landscape, while preserving their ecological, social, esthetic and historic values. These rail areas were often abandoned when industries moved out from the cities, either to industrial areas or abroad. The use of railways for transporting industrial goods was also replaced to a large extent my motorized road vehicles in the mid 20th century, leaving the rails under-utilized. Because of their location and intrinsic values, they can be reused for important functions, such as green areas in the city environment, providing space for recreational activities and exercise and social meetings and interactions. I have closely investigated the three park areas High Line in New York, Promenade Plantée in Paris and Schöneberger Südgelände in Berlin, which have all gone through this transformation in recent years. I have summarized my conclusions in three key concepts to consider: design for social values, preserve the architectural history, and leave room for future evolution. The final part of my work is a design program for an abandoned railways area in Stockholm: Eriksdal railway area.

This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.

The project has been provided by Zenit design group and the goal for this project was tomanufacture and perform tests of a prototype that supersaturates water in a continuous flow ofwater. The project has involved finding and sorting out relevant data in scientific papers, books,communication with foreign manufactures and other platforms for information.The project has resulted in manufacturing of a test rig and an oxygen infuser based onmembrane technology. The test rigs purpose was to perform tests on oxygen infusers fordifferent comparison test and performance benchmarks in a in a laboratory provided by Zenit.The project led to satisfying results using the oxygen infuser manufactured by the authors withcomparable levels of saturation to the reference infuser.The theory behind this project is based on medical research, belonging terms will be explainedbut the authors have chosen to delimit the project from the medical area. The reason for this islack of knowledge in this area and its irrelevance to the mechanical engineering education insuch..

A high degree of urbanization with growing cities has raised a need of transforming closed landfill sites for giving them new uses. This study aims to investigate how old landfills can be re-used, what has lead to the new uses, and for what and whom the transformed site will be an asset. The method used is a case study of four different landfills in Stockholm county, Sweden. The case study is analyzed in the light of former studies regarding re-use of degraded urban areas, so called brownfields, and in particular studies and reports of landfill re-use. The result indicates that old landfill sites is identified as an area with possible values if transformed properly, in the case study area especially as green structure and recreation areas.

I have done a case-study about building a new stable for slaughter pigs at a farm close to Kalmar. The farm is able to supply the breeding with cereals and it has enough area to spread the manure on. The most important factors to gain profit, is the cost for building the stable, the price of the feeding-stuff and the growth of the pigs. The discount from the slaughter-house was less important than I thought from the beginning, and it?s a factor that is hard to influence. With the new production of slaughter-pig and cattle that already exist on the farm, the farm will get a well-functioned rotation of crops with lye and autumn rape as interruption-crop.

This study was conducted to test the hypotheses that a forest managed by selective cutting can store more carbon than a forest managed by clearcutting. The study was carried out as a meta-analysis. The data that was found was analyzed by performing t-tests on the proportional effect that the two silvicultural methods had on the driving factors of CO2-efflux and carbon stores in coniferous boreal forest. In all areas tested, an effect in favor of selective cutting was found, but not all of them significant however. The soil respiration following selective cutting was significantly lower than that of clearcutting, and the primary production of a clearcut area cannot according to reason exceed that of an area post-selective cutting.

The study Packning i tid och rum (Crowding in Time and Space) is a Master Thesis in Human Geography within Geography, presented at Södertörn University College.The aim is to investigate the connections between time and space, more particularly, geographical changes over time. This is done by focusing on the Study of Land use as a phenomenon and on-going processes in demarcated areas. Distinct areas are given special interest, i.e. how they are used. The study deals with three different kinds of sites in three levels of scale: a market garden, cemeteries and a residential area.The main focus of the study is on the cemeteries.

My thesis is a combination of theory and practice, where theory is meant to create a context and a background for my interpretation proposal. I wanted to ?access? the ideas that are always in the background of the reasoning which underlies both planning in a larger scale, and the design of a place. I wanted to make a ?work of ideas.? In the process of shaping the proposal, I wanted to be deleted from the site itself.

Lack of dead wood is the main cause of decaying or loss of populations for many forest species. To increase the amount of dead wood is a prerequisite to maintain biodiversity in forests of northern Europe. In summer 2006 the recreation area Klåveröd, at Söderåsen in Skåne, Sweden, has been inventoried for high stumps (snags) of beech, (Fagus sylvatica). The result of the inventory has been compared with data of the real estate and forest management directories from the owner, region Skåne. The results have also been matched with the results from an inventory of saproxylic beetles in 2005, performed with windowtraps on selected snags both in the area and the adjacent national park Söderåsen. 594 snags were found on 747 ha.

AbstractIn my study I have investigated how a constructed outdoor green environment can beused, managed and how it works. The study also investigates the concept of socialsustainability, where, for example, civil dialogue is a method to promote this. Thisinvestigation mainly gives account for the inhabitants viewpoint but also a gardenersperspective. The study focuses on the planning process of the study object, what theoutcome has been and how the users of the green environment, think about the result. Inthe process there has been a strong concern of involving the residents and others usingthe area.

In the west part of Trelleborg, on previous farmland a new society is under construction. It is situated right next to the ocean and close to the European freeway. Eight types of villages, all with different kind of architecture will be built in the area, one of them is Torns Village built by Skanska and Ikea. A concept called BoKlok. This specific village consists of twelve houses and five apartment buildings. They are all somewhat classical in their appearance with wooden panel, but at the same time they have a modern touch.

To understand the glass electrode needs knowledge from more than one level. The construction ofthe glass electrode is one part, an other is the composition and structure of glass. The Nernstequation have an important role, but also the sources of errors in the analysis and the calibration ofthe glass electrode. Focus for this article is how the glass electrode really works and how Gibbs freeenergy made the potential dependent of the concentration of H+and gives the logarithm to thefunction. Nikolskii's ion exchange theory starts to explain the question about how the potentialcreates and Baucke's dissociation mechanism made it more explicit.

The purpose of this study is to explore how preschool teachers succeed in their mission to conduct work that will enhance children's interest and knowledge in technology. The study was conducted by qualitative semi-structured interviews among eight teachers at seven preschools in the same municipality. The method was chosen because I wanted to get as detailed and full answers as possible. I also wanted to find out their individual perceptions. The result shows that most of the teachers think that they have insufficient knowledge to practically work with technology. At the same time they?re expressing that technology is a broad area that sometimes is a little more complicated than it needs to be.

There are records of lowering of the water level in a lot of the Swedish lakes from the middleof the 1700th century. The aim was gaining more areable land to meet the needs of more foodto support the expanding population. In areas with top soil which contents of clay or loam asin the southwest of Scania in southern Sweden this was proven to be a successful wayexpanding the total outcome of the harvest.The studied area in the northeast of Scania, though, consists of morain with a lot of mires -much less nutritious conditions. When the water level is lowered the atmosphere gets accessto the peat. The dissolving of the organic matter that has been suppressed by the lack ofoxygene below water level continues.
